Abuts

Takes an abut and returns the cell which is equivalent to this abut. Cell resulting always belongs to the from design if me belongs to the from design. It is included in the to design if to#NIL
clipping boundary in object coordinates
clipping boundary in object coordinates
Abuts: Sugared
Rotations
Indirect
In the future, add an IR proc, and maybe a Draw Proc?
Lazy
Tilings
Implementation detail: we could have one sequence instead of a sequence of sequence, it would be simpler.  But it would allow only a limited number of tiles, while this raises the limit.  Once Cedar changes, this can be changed!
Checking all right
Building the array!
clipping boundary in object coordinates
clipping boundary in object coordinates
Implementors goodies
Mechanism for flushing during edits
Having a RefTab (of the right size) helps avoiding frequent allocations.

we include icons of sch
In case obj is a mask, the corresponding sch (if any) "depends" on it.  That's a hack!
We add all the children
Slightly wrong here, because we miss the objects which are NOT in the directory (e.g. unnamed cells)
If the object may be simplified (small average size), display bbox and name if available and return TRUE, otherwise do nothing & return FALSE.
Factor is 50.0 for cells. Making it larger makes it harder to detail a class of objects.
This is for the use of Quick DrawProcs, in order to have a standardized clipping algorithm
The algorithm mimics the one implemented by CDCellsImpl
Utilities for debug

Commands
-- Generate the object
-- Now figure out how long it took to generate this wonderful piece of layout
Silly line, just because CD does not do the right thing!
